PROBLEM TO BE SOLVED: To achieve a structure capable of controlling a pixel for focal point detection independently from another imaging pixel while maintaining sensitivity of an imaging element to achieve good image quality.SOLUTION: An image pickup device has a first semiconductor chip and a second semiconductor chip which are stacked one on the other. The first semiconductor chip has a pixel part composed of first pixel group and a second pixel group, and a first drive circuit for driving a pixel of the first pixel group. The second semiconductor chip has a second drive circuit for driving a pixel of the second pixel group. 【課題】 撮像素子の感度を維持し良好な画質を得ながら、焦点検出用画素を他の撮像画素とは独立に制御することが可能な構成を実現すること。【解決手段】 撮像装置は、互いに積層された第１の半導体チップと第２の半導体チップを有する。前記第１の半導体チップは、第１の画素群及び第２の画素群からなる画素部と、前記第１の画素群の画素を駆動する第１の駆動回路とを有する。前記第２の半導体チップは、前記第２の画素群の画素を駆動する第２の駆動回路を有する。【選択図】 図１
